Automatic flying machines and shoving other people's reses

Ugh, I'm sorry. I just now found the thread which already addressed this concern. I understand now. That being said, I am very excited about the ways that we'll be able to use slime blocks in 1.8. The new possibilities that slime blocks will present for red stone machinery are going to be absolutely delightful.

It will probably work like if you were trying to use a piston to push stuff onto the street. The piston simply doesn't budge. Since the flying machine is run by pistons, it should not cause a problem for residence owners in town.

okay cool. I was thinking about the fun I'm going to have with it and then I thought "uh oh.. what if someone sets one of these loose on the town?" Now I realize that the code is already written such that the signal gets cancelled at the res border.
